The first one is about a baseball signed by a star, and the second one is about a rocket model. Similarly, they all moved these items to the site guarded by the legendary big dog.

Plot:

Smalls loves baseball, but he is not good at it, so he is laughed at by other children. Fortunately, Lebani taught him to play enthusiastically. A big German shepherd in the backyard of the stadium often takes the opportunity to hide their balls. In the eyes of these children, they are simply "animals". One day, Smalls stole Babe Ruth's signature ball to play ball, which was regarded as a treasure by his stepfather. Unfortunately, he hit the ball into the backyard. That's great. How did they manage to get it back completely?
